4 basic laws of thermodynamics correct answers zeroth law: states that 2 objects in thermodynamic equilibrium with a 3rd object are also in equilibrium with each other 1st law: states that neither mass nor energy can be destroyed; only converted from 1 form to another(conservation of energy) 2nd law: states that the entropy of an isolated system can only increase; heat is not transferred from low temp system to a higher temp system one unless additional work is done 3rd law: states that as a temperature approaches absolute 0, entropy approaches a constant minimum; system can not be cooled to absolute 0. compare and contrast heat and temperature correct answers heat: energy transfer from 1 body or system to another due to thermal contact temperature: measurement of an object's stored heat energy mass correct answers measures how much of a substance is in an object weight correct answers measures the gravitational pull of the earth on an object density correct answers a measure of the amount of mass in a given volume D=m/V volume correct answers measures the amount of space taken up specific gravity correct answers measures the ratio of a substance's density to the density of water thermal contact correct answers energy transferred to a body by a means other than work heat correct answers The energy transferred between objects that are at different temperatures Models for the flow of electric charge correct answers used to explain the flow of electric current, potential, circuits include water, gravity and roller coasters magnetic field correct answers motion of subatomic structures(nuclei and electrons) produce magnetic field; formed not only by magnetic material but also by electric current flowing through a wire magnetic moment correct answers The strength of a magnetic field electric charges as they relate to atomic structure correct answers electric force: attractive force between the electrons and the nucleus
